I imagine there was a meeting at TomTom some months ago where it was decided, for whatever reason, that there was a need for them to bring their own maps and navigation apps to Android. Now, after who knows how long, those apps have come to fruition. Only they're quite expensive ($38-$60), and not compatible with, well, any modern device. Not the HTC One X, Galaxy Note, Galaxy S III, or Galaxy Nexus.
